Not only because of genetics..why do some Africans have blue eyes
The origin of black people with blue eyes is no different from the origin of the color of any human being. The decisive factor is heredity
Black people are affected by this genetic mutation in the same way as any other human being, but since this mutation originated in Europe, it is rare to see a black child born with blue eyes. Another, but less common, reason why a black child is born with blue eyes is if he has ocular albinism or Waardenburg syndrome.
